Identify chemical reactions in terms of reactants and products
List factors affecting the rate of reactions

To Dos:
Compare pennies: Why is this one brown and dull and this one is shiny?
Because the oxygen from the air reacted to the copper on the penny forming a copper oxide layer...
Penny & Hot Sauce Experiment
Today we're gonna talk about Physical Changes and Chemical Changes...
Give definition!!...Physical Change: A change that effects only the size and shape of a substance or whether it becomes a liquid, solid, or gas...
Can someone give me an example of a Physical Change: Ice melting into water...
What happens if __ holds this ice cube throughout class?
Why is Ice melting into water a good example of a physical change? Because it's still water; it only changed from a solid to a liquid...
What then is a chemical change?
Chemical Change: A change that produces new substances that have properties different from the original substances...
What is an example of a chemical change that we've already talked about? Oxygen mixing with the copper to form a copper oxide...
Why is that a good example of a chemical change? Because the copper from the penny is changing because of a reaction to the oxygen...
Define: Chemical Reaction: A process that produces chemical change...
Give me an example of a Chemical Reaction: The hot sauce reacting with the copper oxide...
Tape "Before" and "After" Pennies into Science Journal

To Dos:
Review: What is an example of a physical change? / What is an example of a chemical change? / How is a physical change different from a chemical change? / What is an example of a chemical reaction?
Read page 38, "Chemical Equations" and in your Science Journal define Reactants and Products
What is a Reactant?
Reactant: Substances that exist before a chemical reaction begins
What is a Product?
Product: The substances that form as a result of a chemical reaction
Experiment: What do you think will happen when I mix baking soda and vinegar?
In this experiment what are the reactors? (Baking Soda & Vinegar)
What are the products? (Gas & White Solid)

To Dos: Make Copies of Chemical Reactions Key Terms Worksheet (Chemistry/Ch 2/pg 22)
Review: In our baking soda experiment what was one of the reactors? / What was the other reactor? / What was one of the products? / What was the other product? / Give me a definition of a reactant / Give me the definition of a product
Complete the Key Terms Worksheet by reviewing pages 46-52
